Seasickness is often dismissed as an inconvenience or a passing discomfort, but it can become debilitating – even for seamen. Working at sea is demanding under the best conditions, and when chronic seasickness strikes, it can jeopardize not only a worker’s health but also their ability to perform essential duties safely.
For those who make their living on vessels, persistent seasickness raises important questions about medical treatment, job security and legal rights under maritime law and the Jones Act.
What causes seasickness?
At its core, seasickness is caused by the body’s struggle to reconcile conflicting signals from the inner ear, eyes and brain regarding movement and balance. While most people eventually adapt to motion at sea, some never fully adjust. Severe cases can lead to nausea, vomiting, dehydration, dizziness and extreme fatigue. When these symptoms occur regularly, they can impair a seaman’s ability to carry out tasks, compromise safety aboard a vessel and even contribute to accidents that could place the crew and ship at risk.
Employers in the maritime industry have a duty to provide a reasonably safe working environment. This includes addressing medical issues that impair a seaman’s ability to work. If a crew member becomes debilitated by seasickness, the employer may be required to provide medical attention, adjust work duties and, in some cases, arrange for the seaman’s return to shore for treatment. A failure to take such steps can lead to claims for negligence or unseaworthiness if the seaman suffers harm as a result.
Under the Jones Act, seamen who suffer injuries or illnesses related to their service on a vessel are generally entitled to maintenance and cure. Maintenance provides for daily living expenses, while cure covers necessary medical treatment until the seaman reaches maximum medical improvement. This protection applies even when an illness is not directly caused by negligence, so long as it arises during the course of employment. For seamen with severe seasickness, these benefits may be necessary when it comes to securing care and financial stability after an illness that proves debilitating.
Debilitating seasickness is sometimes not simply an inconvenience for those who spend their lives at sea—it can be a career-threatening condition. Seamen who find themselves unable to work safely because of seasickness have rights. Seeking legal guidance is a great way to learn more.
